Per-service opt-ins (booleans) recorded on 195 the device and applied to its private node at hotplug, selecting 196 which mm services may act on the node's memory. A private node 197 opts out of everything by default; each toggle relaxes one 198 service: 199 200 reclaim allow reclaim of the node's folios, by the mm 201 and by userspace MADV_COLD/PAGEOUT/FREE 202 mempolicy allow userspace placement policy 203 (mbind()/set_mempolicy()/home_node) onto the node 204 hotunplug allow hot-unplug via migration 205 tiering allow kernel access-aware migration: demotion 206 target, NUMA balancing, and DAMON migration 207 ltpin allow FOLL_LONGTERM GUP pins 208 user_migrate allow userspace move_pages() to/from the node 209 210 Writable only while the device is "unplugged" (-EBUSY otherwise). 211 Dependencies between opt-ins (tiering requires reclaim) are 212 validated when the device is hotplugged, not 213 at write time: an inconsistent combination is accepted by the 214 write but the subsequent hotplug then fails. 215 See Documentation/mm/numa_private_nodes.rst. 216 -- 0-DAY CI Kernel Test Service https://github.com/intel/lkp-tests/wiki
